Method and device for learning generating lane departure warning (LDW) alarm by referring to information on driving situation to be used for adas, v2x or driver safety required to satisfy level 4 and level 5 of autonomous vehicles

Abstract

A method for generating a lane departure warning (LDW) alarm by referring to information on a driving situation is provided to be used for ADAS, V2X or driver safety which are required to satisfy level 4 and level 5 of autonomous vehicles. The method includes steps of: a computing device instructing a LDW system (i) to collect information on the driving situation including information on whether a specific spot corresponding to a side mirror on a side of a lane, into which the driver desires to change, belongs to a virtual viewing frustum of the driver and (ii) to generate risk information on lane change by referring to the information on the driving situation; and instructing the LDW system to generate the LDW alarm by referring to the risk information. Thus, the LDW alarm can be provided to neighboring autonomous vehicles of level 4 and level 5.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. patent application Ser. No. 16 / 263,220, filed 31 Jan. 2019, the entirety of which is hereby incorporated by reference.FIELD OF THE DISCLOSURE[0002]The present disclosure relates to a method and a device for use with an autonomous vehicle; and more particularly, to the method and the device for generating a lane departure warning (LDW) alarm by referring to information on a driving situation.BACKGROUND OF THE DISCLOSURE[0003]In the last 2015, about 1,747,000 traffic accidents occurred in the United States. At this time, 35,092 people were killed by traffic accidents. The number of deaths per 10,000 vehicles was 1.2 and the number of traffic accidents per 100,000 people was 10.9, which is the highest death rate among OECD countries. As can be seen from the statistics above, the problem of traffic accidents in the United States is very serious and it will be very important to prevent them.[0004]Traffi...

Benefits of technology

[0007]It is another object of the present disclosure to reduce an accident probability of a driver by generating a lane departure warning (LDW) alarm by referring to whether a specific spot corresponding to a side-view mirror on a side of a lane, into which the driver desires to change, belongs to a virtual viewing frustum of the driver.

[0008]It is still another object of the present disclosure to send a warning signal to the driver more efficiently by adjusting an intensity and a frequency of the LDW alarm by referring to types of lanes or those of lane markings.

Problems solved by technology

If one does not take a good look around when changing lanes, his or her vehicle is prone to collide with the cars in the surrounding lanes.

However, a conventional lane departure warning (LDW) system merely detects whether a vehicle deviates from the lane but does not detect whether the driver takes a good look around during the lane change.

Further, even when giving a warning to the driver, it is performed in a monotonous way, and thus it cannot satisfy needs generated by various driving environments.
